The structure includes a main side member and passes thenceto screen 46'mou'nted for 10 extending longitudinally on the right side longitudinalmovement by transverse rock of the machine, and a similar element 11 onshaft 47, connected by'l i-nks 48 with the inner the left side, thesemembers being connected end of the-screen; Hangers 48" each, include Tfor example by transverse rods 12. The forreversely extending endportions permitting ward and rear axles 13 and 14 have their mountingand oscillating movement of the screen, between the side members. Shaft47 carries wheel l9 driven by chain 50 passing over wheel 51 on uppertransverse shaft 52 carrying the roller and wheel 53 to which rotationis imparted by chain 55 and wheel 58 on the rear axle of the machine.Ihis axle mounts the ground wheels before referred to.

One of the meshing and crushing rollers is mounted on shaft 58 havingwheel 59 driven by chain 60 and wheel 61, on the rear axle of themachine. Above screen 46 is a pair of rollers 64, 65, mounting belts orchains 66 and cutter bars or knives 67, each comprising angle members asshown are carried by the elements 66, and separate the material passingover delivered to a receptacle or box 68 secured to the side elements 10and 11 of the main structure and having a capacity of say 300 pounds.

No grass or roots should be permitted to return to the ground, becausethey will within a short time start a new growth. The machine is capableof removing a large amount of grass and the roots thereof, and ofconverting them into condition for removal under the most favorablecircumstances, so that accidental discharge by wind or the like can beavoided.

What I claim is i 1. In a grass digging machine, a main structure,forward and rear axles mounted therein, a scoop-like digging device,hangers for supporting this device in the main structure, and connectedwith the scoop rearwardly of the point of engagement of said diggingdevice with the ground below the forward axle of the machine, meanscontrolling the vertical position of the hangers, rotary cutters mountedat the forward portion of the digging device, a crank shaft in the mainstructure, a lever controlling the shaft and element connecting thecrank shaft with the rear portion of the scoop-like digging device forchanging the depth at which the scoop is operative.

'2. In a grass digging machine, a main structure, axles mounted therein,a digging device, hangers for supporting this device in the mainstructure, means controlling the vertical position of the hangers, aconveyor extending upwardly and rearwardly from a point within thedigging device, and a screen connected with and extending into thedigging device, said screen being substantially parallel with theconveyor and below the path of travel thereof, a crank shaft in the mainstructure, a lever controlling the shaft and element connecting thecrank shaft with the rear portion of the digging device for changing theelevation thereof.

3. In a grass digging machine, a main structure, axles mounted therein,a digging device, hangers for supporting this device in the mainstructure, means controlling the vertical position of the hangers, acrank screen 46, the material being then shaft in the main structure, alever controlling the shaft and element connecting the crank shaft withthe rear portion of the digging device for changing the elevationthereof, meshing rolls for receiving material discharged by theconveyor, an oscillating screen extending rearwardly from the rolls, andmeans including a crank shaft for imparting movement to the screen, anda screen extending into and connected with the digging device,thisdevice being subject to movement during adjustment while the screen issubject to limited responsive movement.

4. In a grass digging machine, a main structure, axles mounted therein,a digging structure, a digging device mounted in the forward portion ofthe main structure, elevating means operative from a point intermediatethe ends of the digging device for conveying material from said diggingdevice, crushing rolls positioned rearwardly of the elevating means, alongitudinally movable screen extending below the rolls, mechanism foractuating the elevating means, and means for reciprocating the screen bysaid mechanism actuating the lifting means.

6. In a grass fdigging machine, a main structure, a digging devicemounted in the forward portion of the main structure, elevating meansfor conveying'material from a point directly within the diggingdevice,crushing rolls positioned rearwardly of the elevatingmeans," alongitudinally movable screen extending below the rolls, mechanism foractuating the elevating means, a rear axle for the machine, means fordriving the rolls from the axle, and independent means for driving themechanism actuating the elevatmg means and screen from said rear axle.In testimony whereof'I affix my signature.

FRANK KINGH.
